You loved Lea Michele's. And what's not to love about Kristin Cavallari and Amber Valletta's? Absolutely nothing. They're sexy, they're fun, they turn heads, they are hot little frocks . . . in a rainbow of candy colors. Amber is perfectly posing in Roland Mouret's orange Rainbow collection dress, while Kristin chose my favorite color as her birthday dress last weekend. It's the middle of January — not everyone can pull these off right now — but they'll serve as perfect wedding attendee dresses and hot-date fodder for the Spring, so start your ShopStyle search engines.
